Got around to tweaking after a quick crit. Wasn't liking something about his face, he looked like a meal dodger so rounded it out a little while also scaling up the entire head a tad (the image below isn't lined up properly) to achieve more child-like proportions.
One more thing that was pointed out is that his shoulders were too broad. Looking at the comparison below the difference is striking. When it comes to making Odin I'll sculpt the complete piece in one instead of the head separately like I did with Thor to hopefully avoid missing key proportions.
